Abstract

The reactivity and stability of 1,3-benz-azaphospholes. 1,3-benzo-diphospholes respectively their anions arc investigated by means of quantum chemical calculations. The results are compared with experimental data. They represent all qualitative aspects of the chemical behaviour. Especially it is shown that the extraordinary stability of the 1,3-benzo-diphosphole anion may be due to its electronic structure (corresponding to a benzo-bridged heteroallyl anion).

Reaktivität und Stabilität von 1,3-Benzazaphospholen und 1,3-Benzodiphospholen sowie deren An-ionen wurden mit Hilfe quantenchemischer Berechnungen untersucht. Die Ergebnisse wurden mit experimentallen Daten verglichen und repräsentieren alle qualitativen Aspekte des experimentellen Verhaltens. Insbesondere konnte gezeigt werden. Daß die relative Stabilität des 1,3-Benzodiphospholyl-Anions auf seine Elektronenstruktur. einem benzoüberbrückten Heteroallylanion. Zurückzuführen ist.
